- Abstract:
- In this paper,the shear wave splitting method is used to study the active source data of Binchuan area.The active seismic data were recorded during Novermer to December 2015.We analyzed the splitting parameters,the results are as follows:(1)The average fast polarization direction is 25.1°,and the average slow wave delay is 0.006s/km.(2)The fast direction are descreasing from -9°to -66°in Binchuan area,this may be caused by the intersection of the Chenghai fault and Red river fault.(3)During the study period,three earthquake with ML larger than 1.0 occurred.No variety was observed before and after the three earthquakes.
